[Dysostosis cleidocranialis--a case report]

An 18-year female patient with dysostosis cleidocranialis, treated for dental anomalies characteristic of her basic disease since the age of 12, is described. Delayed resorption of deciduous teeth and eruption of permanent teeth were recorded. At the age of 12, the patient had still had all deciduous teeth, with the exception of lower incisors and right upper mesial incisor. The presence of 11 succedaneous teeth, 7 in the maxilla and 4 in the mandible, had been recorded by X-ray. The treatment performed step by step is presented. Firstly, deciduous teeth were extracted, and a prosthesis for both the maxilla and mandible were constructed to stimulate eruption of permanent teeth. All supernumerary teeth from the jaws were also surgically removed. After the permanent tooth eruption had been accomplished, orthodontic treatment of these teeth was required and it has still been successfully performed. Thus, a conclusion is made that the treatment of dental anomalies should start at the time of normally expected deciduous tooth exfoliation.
